Manual window operation?? xk8 coupe
 

Hello all, thanks in advance for any replies/assistance. I purchased a used xk8 coupe door from a salvage yard, and I'm wondering if there is a way to "push" the window glass down manually, or manually operate the motor keeping in mind the door is not attached to a power source. I'm unable to move the window at this point and having trouble getting to the clips that hold the glass on the regulator. And...could that indicate a seized motor?
